| Description | Glabranin has antimicrobial activity, it shows significant activities on DPPH free radical with the IC50 value of 240.20 ug/ml. Glabranin or a derivative thereof could be used to stimulate hair growth. Glabranine exerts a dose-dependent inhibitory effect in vitro on the dengue virus, it presents 70% inhibition on the dengue virus at a concentration of 25 microM. |
| In vitro | The ethyl acetate and methanol bark extracts of Melicope glabra were evaluated for their antioxidant capacities by 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging activity and β-carotene bleaching/linoleic acid system. Both extracts exhibited strong inhibition against the DPPH radical (IC50 values of 24.81 and 13.01 μg ml(-1), respectively) and strong antioxidant activity in β-carotene bleaching assay. Both samples were found to have high phenolic content with values of 39 and 44 mg GAE/g as indicated by Follin-Ciocalteau's reagent. Antioxidant TLC assay-guided isolation on the methanol extract led to the isolation of a new pyranocoumarin, Glabranin (1), umbelliferone (2), scopoletin (3) and sesamin (4), and their structures were determined by spectroscopy[1] |
